IVILLIAM H. BLISS, OF NEWPORT, RI-IODE ISLAND; EDIVARD NEIVTON ADMINISTRATOR OF SAID IVILLIAM II. BLISS, DECEASED.

FURNACE FOR DESTROYING REFUSE MATTER.

SPECIFICATION forming part of Letters Patent No. 395,807, dated January 8, 18189.

Application filed November 16, 1887. Serial No. 255,305. (No model.)

To all LLhOIIb it may concern:

Be it known that I, IVILLIAM II. BLISS, of Newport, in the county of Newport and State of Rhode Island, have invented a new and Improved llurnace for (arbonizing and Destroying Refuse Matter, of which the following is a full, clear, and exact dcscriptimni.

My invention relates to a furnace construoted for destroying or earli onizing refuse matter, and which is intendeiil more particularly for the disposal of house garbage, offal, and other substances, utilizing the same either as fuel or fitting it for use as fertilizer.

The invention consists, principally, in constructing the furnace with rctorts in which the refuse is subjected to heat, said retorts being connected to fines leading back to the fire-grate, so that the fumes and gases will be consumed in the furnace.

The invmition also consists in connecting the retorts with inclined chutes leading to the furnace, so that the material in the retorts, after having been carbonized. or reduced to dryness, may be discharged into the furnace and burned.

The invention alsoconsists in so constructing the furnace that the contents of the retorts may be discharged into a chamber or other receptacle and used for fertilizer.

The invention finally consists of the con struction, arrangement, and combinatimi of parts, all as herei 11 after describwl and cl a i med.

Reference is to be had to the accompanying drawings,forming a part of this speci tication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 a sectional elevation of my improved furnace, taken. on the line a a; of Fig. f. Fig. 2 is a similar view taken on the line y y of Fig. 4.. Fig. 3 is a transverse sectional elevation taken on the line .2 A: of Fig. 1. Fig. i is a plan view and Fig. 5 is a sectional plan on the line .r ax of Fig. l, the right-hand retort being removed.

The furnace is constructed principally of masonry, and should be about twenty-two feet long and eleven feet wide, and stand, without the chimney, about twenty feet in height. There is a space, A, inside of the walls at each end of the furnace six feet in width and nine of the carbonized matter from the retorts B above, which matter may be used as fertilizer. Two division-walls, C, of brick separate these chambers A from the ash-spaces D D and return-fines E These division-walls extend to the top of the structure and form the sides of the fines E. Said two returirflues E E are closed at the top by the walls E, and they start from the ground, and the two ash-spaces D formed by the division-wall I) connect each with one of the said return-fines. E is the wall that separates the flues E E. E is the back wall of the structure, E the front wall, and E and are the end walls thereof.

F represents the fire box. or furnace proper, provided with the grate-bars F at the bottom. The rctorts B are held in chambers 13 B, and are by preference made of wroughtiron and funnel-shaped at the bottom, terminating in a tube or collar, Said spaces or chambers B communicate with the furnace F through the inclined fines G, so that the heat from the furnace passes through said fl ues and first strikes against a deflecting-wall, H, of fire-brick, arranged to protect the cones of the retorts from the direct action of the heat. This wall H is separated from the cone by the air-chamber H. The heat passes to the edge of this wall, thence circulates around the cones of the retorts below the plate H as shown by the arrows in Fi 5, and then passes back and circulates around the main body of the retort, again above said plate Hiand thence into the chimney-flue through openings or passages TI. (See 2.)

The rctorts rest against the inner walls, 0, at a, being separated at all other parts by an 'air space or fine six inches, or thereabout, in

width at the smallest distance, as shown at a, in Fig. 5. The space I above the furnace F is formed for the purpose of receiving a steam-boiler, to be used, if desired, for gen.- erating steam. for power.

Below the retorts are built into the walls the inclined chutes J, with which the retorts are connected by means of the tubes or col lars B Each chute J is provided with two valves, J and J the former closing the tube B and the latter closing a correspondingopening at the bottom of the chute. These valves are operated by means of rodsjj, reachin g to the outside of the furnace, and they are adapted for such operation that the contents of the retort can be discharged into the furnace F or into the chamber A, If both valves are opened, the contents will drop into the chamberA; but if only the valve .1 be opened the contents will drop into the chute J and slide down the same into the furnace F, where it will be consumed as fuel. Openings I) Z) are formed at the outer ends of the tubes to admit of the insertion of a rod or plate for cleaning the chutes, and dampers N N are placed in the chimney-openings 1-1 H. to cut off the flame from the retort at the time of discharging its contents.

M M represent pipes connecting" the rctorts with the :flues E E, by which the steam and gases generated within the retorts are carried down to the bottom of the furnace l1 and discharged nnder the grate-bars F, and pass thence up to the fire in the furnace, where they are destroyed, so that no odors escape from the furnace.

The retorts are tightly closed by the large annular covers 0 O, in each of which is formed a small cover, 0, which is to be removed to introduce small substances into the retorts Without removing the large covers; but when bulky substances are to be introduced the large cover 0 may be removed.

Having thus described my invention, what I claim as new, and desire to secure by 'Lettors Patent, is

l. A furnace for destroyin re fuse material, constructed to form a tire-chamber, F, side retort-chainbers, 13, side lines, G, connecting the furnace with the said retort-chambers, and the return-Flues E, eonnectin the retort-chambers with the furnace F below the fire-grates ls", substantially as and for the purposes set forth.

2. In a furnace for destroying refuse material, the lire-chamber l and connected reiort-cha'mbcrs l3 and retorts B, in combination with the chutes J, connecting the retorts with the fire-chamber, substantially as and for the purposes set forth.

3. The iretorts l3, return-lines E, and the pipes M, connecting the said retorts with the said return-fines, and the fire-chamber 1 connected with the return-fines, and thepassages G, connecting the fire-box to the retort-spaces, in combination with the chutes J, valve J, chambers A, and valve J substantially as and for the purposes set forth.
